It's just as well that 256GB is enough for anyone. Maybe I'm pre-empting the next part in this series, but it looks like simply scaling NAND flash geometry might be a dead end: "While the growing capacity of SSDs and high IOP rates will make them attractive in many applications, the reduction in performance that is necessary to increase capacity while keeping costs in check may make it dif- ﬁcult for SSDs to scale as a viable technology for some applications." http://cseweb.ucsd.edu/users/swanson/papers/FAST2012BleakFlash.pdf http://cseweb.ucsd.edu/users/swanson/papers/FAST2012BleakFla...

While SSDs are still scaling, like you said they won't scale forever. Memristors have just recently been proven to exist and there are a lot of companies showing that they have working memristors. I hope that by the time we reach "peak silicon" on SSDs, memristors will be there to pick up the slack. They've been a long time coming, but now that they finally exist we should be seeing them soon. According to HP, they should have memristors on the market in about 6 months. http://www.dailytech.com/HP+to+Deploy+Memristor+Powered+SSD+Replacement+Within+18+Months/article22963.htm http://www.dailytech.com/HP+to+Deploy+Memristor+Powered+SSD+...

We will probably use a combination of SSDs for speed and HDDs for storage for a long time. I don't think it's cost effective to keep everything on a SSD (like: movies), as the cost/GB is ~15x higher than the HDD storage. I have a combination of SSD+HDD in both my machines (desktop: first-generation 40GB SSD + 2TB 7200rpm HDD, laptop: 128GB SSD + 500GB 7200rpm HDD) and I get the best from both worlds: cheap storage for large files on HDDs and fast OS and applications on SSDs. Because of this combination I don't feel the need to use a bigger (and costly) SSD.
